-----------------------------------------
Hi Punith,
I am glad to hear that :)
You can find the source code repository here:
https://git-wip-us.apache.org/repos/asf?p=olingo-odata4.git
Here is a tutorial on how we would prefer the patch file:
http://olingo.apache.org/contribute.html
If you have questions or want to discuss architecture or implementation
decisions you can use the comment mechanism here.
There are two ways to solve this IMHO:
1. Make the deserializer EDM aware (My personal favourite but more
implementation work)
2. hava a post-deserilaization method that checks which properties have been
deserialized and if they need a different value object in case they are comlex
or navigation properties.
It would be very helpful to include a test to show that the changes work and to
prevent future refactorings from breaking the new behavior.
Best Regards,
Christian

> Key: OLINGO-1064
> URL: https://issues.apache.org/jira/browse/OLINGO-1064
> Project: Olingo
> Issue Type: Bug
> Components: odata2-core, odata4-client, odata4-commons
> Affects Versions: (Java) V4 4.2.0
> Reporter: Punith DG
> Assignee: Christian Amend
> Attachments: complexType.png

> The ODataClient deserializer wrongly converts the Complex Type field to
> Primitive Type field if the value received for the complex type is NULL.
> e.g. on querying Person data from OData TripPin service
> (https://services.odata.org/TripPinRESTierService) I received below JSON
> response.
> {
> "@odata.context":
> "http://services.odata.org/TripPinRESTierService/(S(myhztseklikbg41mbg03ugk5))/$metadata#People(AddressInfo,FavoriteFeature,FirstName,HomeAddress,LastName,UserName)",
> "value": [{
> "FavoriteFeature": "Feature1",
> "FirstName": "Angel",
> "Gender": "Female",
> "LastName": "Huffman",
> "UserName": "angelhuffman",
> "AddressInfo": [{
> "Address": "55 Grizzly Peak Rd.",
> "City": {
> "Name": "Butte",
> "CountryRegion": "United States",
> "Region": "MT"
> }
> }],
> "HomeAddress": null
> }]
> }
> See that 'HomeAddress' is ComplexType of type 'Location' and received 'null'
> value.
> Similarly, ComplexType property 'City' is deserialized as Primitive Type in
> the below response.
> "HomeAddress": {
> "Address": null,
> "City": null
> }
> When you deserialize and get an entity, the HomeAddress property of the
> Person entity is set to Primitive Type with null value. This could be complex
> type?
